- The present invention generally relates to an apparatus for communicating, and in particular, to an apparatus for communicating amongst individual passengers within a vehicle.
- The automotive industry is increasingly focusing on improvements within the interior of the vehicle. Innovations in technology and design have increased passenger comfort and satisfaction. One recent innovation, particularly in larger vehicles such as minivans and sports utility vehicles, is the in-vehicle entertainment system. Such systems may include one or more electronic components. A few examples of in-vehicle entertainment systems include televisions, stereos, digital versatile disc players, video game consoles, and computers.
- In-vehicle entertainment systems provide a variety of entertainment options. For example, passengers may use the in-vehicle entertainment system to watch television or recorded videos, listen to music or play video games. The in-vehicle entertainment system is particularly useful in providing children with activities during long trips.
- However, the in-vehicle entertainment systems may interfere with communication amongst passengers. For instance, if the in-vehicle system is playing loudly, it may cause difficulty in communication between passengers sitting in the front and passengers sitting in the back. The communication problem is compounded by the fact that the passengers in the front seats are facing forward with their backs to the passengers in the rear seats, and thus their voices project towards the windshield. Communication is even more difficult for the driver, who cannot safely turn around to communicate with passengers in the rear seats.
- An in-vehicle entertainment system comprising an entertainment device configured to broadcast an audio signal, at least one set of headphones configured to receive the audio signal; and at least one microphone coupled to said entertainment device, wherein the entertainment device is configured to selectively attenuate the audio signal and to broadcast a mixed audio signal to the headphones when the microphone is activated.
